GPGPU (General-purpose computing on graphics processing units) is the means of using a graphics processing unit (GPU), which typically handles computation only for computer graphics, to perform computation in applications traditionally handled by the central processing unit (CPU).

There are many specs given about a GPU. I want to know by which single factor its performance can be measured; would it be based on pixels/sec, clock speed, number of cores, amount of memory, memory ...

Is there such a point where using GPU Processing or Coprocessors (such as the Intel Xeon PHI card or the Nvidia Tesla card) can actually reduce the speed of which a software computes data?
Say I had ...

I want to execute OpenCL code on a PC which doesn't have a graphics card, nor any other hardware component which is able to execute OpenCL. Is it possible compile my OpenCL code in a way that it can ...

I have a Windows calculation-intensive solution that uses NVidia's GPGPU (CUDA).
I am looking to host my application on the cloud and expose it via a Web service.
The only host I found was AWS, but ...

I'd like to use a Tesla C2075's VGA (D-SUB) DVI output. I installed the latest Quadro driver (as suggested by the NVIDIA driver finder) on the 64-bit Windows 7, but it doesn't seem to be working. E.g. ...

I am trying to build a PC capable of running in the best case both GPGPU-sim and BARRA sim. And if impossible to match I am going to stick with GPGPU-sim.
Below is a list of software requirements and ...

I have a GTX570 in a win7 machine that I use for CUDA GPGPU work. I am getting some device timeouts; the solution to this is to perform computations on a second card with no displays extended to it.
...

I'm doing some machine learning work that benefits tremendously from using the GPU. I'm kind of at the limits of my current setup (A workstation with a single GTX580) and I really don't have room for ...

After a kernel fails due to "unspecified launch failure", the only way I am able to use the device again is after a system reboot. Is there another way to do this? If I attempt to to run again after ...

First of all, this is for a GPGPU project so I only need a very small amount of bandwidth. The bandwidth for PCI and PCI-e 1x slots are several orders of magnitude more than I need.
Some people have ...

I'm new to GPU-programming with CUDA and have just installed everyting on my machine to get started, and it's working. Big victory! However, when I open the code samples in VS(2005 and 2008) NVidia ...
